team alpha hop issue

finaly got my team alpha cqb but after takeing it to a game today i quickly realised i had a max range of about 15 feet! not realy what i wanted.... when i look down the barell and adjust the hop screw i cant see anything happening surely there should be a nub of some description becomeing visable? hop all the way on or all the way off makes no difference, must have got a lemon of a hop unit does anyone know if i need to send it back to the shop i bought it from or do i send it direct to s.t.t.s?

hop unit is silver ish same kind of metal as the gearbox shell.when i look down the barell i cant see anyhing on the top or bottom of the barell though i am just looking down it with the gun in the "broken" position removed cylinder and looked from the hop end then looked from the other end and still cant see anything.left hop unit and barell still instaled... since i havnt figured out how to remove it yet

Pull the barrel out (if its tight take off the flash hider - undo the 1.5mm grub screw securing it on first) and and this will expose the barrel. Push down on the floor and it should push it free of the inner barrel and then pull it out.

Hold to the light, look down it and adjust the alen key with the driver supplied and see if you see anything happening from the top - the barrel should go from round to a 'D' shape with the flat bit being at the top.

If nothing happens then its simply out of align - take back to where you got it and they will have it sorted in minutes.

maybe i will wait until the warranty runs out before i attempt glueing the wrong part, if you find out what needs to be done dont forget to post it for the rest of us . have been reading up on tackleberrys super hop wouldnt mind forking out the cash and getting one if i knew it would fit in the team alpha ctw's

Glueing is ok until it only glues the hop-up rubber. To have more consistent shots, the hop rubber should stick in place. As a reference, see the normal AEG hop up rubber - there are no things to move.

turns out i was expecting a bit much from the ctw i think.. its no worse than a standard aeg but its also no better accuracy and range wise.... have seen mod'd ptw 's with some wicked range and accuracy its a shame people are so secretive about how to do these mods

In THEORY a rolling hop nub could work, as you would get a smoother action and reaction on the BB - But in practice , the hop rubber spins inconsistently and too easily in some guns ,therefore is always applying a different load ,as it can turn erraticaly and with heavier bbs cannot exert enough force (so you glue the nub, to stop the rotation) ideally, from the standard CTW a larger roller nub that can roll a little and consistently would be the ideal.But it is very difficult to perfect on a production gun! Hence the easiest fix being to stop the rubber moving and give consistensy to the bb hop - but it is not the ultimate tune up.
